Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

DNA repair mechanism: HELQ helicase remodels stalled replication forks into stable structures, preventing harmful mutations under replication stress. Advanced imaging tool: RF-SIRF maps reversed forks ...

Alphabet Inc.’s Google DeepMind today introduced AlphaGenome, a new artificial intelligence tool that can comprehensively predict how mutations or variants in human DNA sequences impact gene ...

Mitochondria are well known as the powerhouses of the cell because of their energy generating capabilities. These little organelles are very special, because they also carry their own tiny little ...

Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding ...

Origins of the code: University of Illinois researchers found that the genetic code’s origins are tied to dipeptide composition, offering clues to life’s earliest evolution. Beyond coding DNA: Most ...

Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

The microbial toxin colibactin has just the right shape to snuggle up to DNA — but its embrace is unfortunately more cancerous than cozy. Colibactin is produced by bacteria in the gut and causes ...
